In open-chest dogs, T wave changes were recorded following coronary occlusion and sympathetic nerve stimulation. Recording of suction electrograms was made to study their genesis. Not only after release but immediately after introduction of coronary occlusion, T wave was inverted significantly associated with QT prolongation in sites with prolonged excitation duration in suction electrogram. Sympathetic nerve stimulation also produced T inversion followed by rapid reversion to positive T wave, which was apparently analogous to ischemic changes in electrophysiological aspects. However, the underlying mechanisms were thought to be much different.
在开胸犬中，记录了冠状动脉闭塞和交感神经刺激后的T波变化。进行了吸引电图记录以研究其发生机制。不仅在解除冠状动脉闭塞后，而且在引入冠状动脉闭塞后立即，在吸引电图中兴奋持续时间延长的部位，T波倒置并伴有QT间期显著延长。交感神经刺激也产生T波倒置，随后迅速恢复为正向T波，这在电生理方面显然类似于缺血性变化。然而，其潜在机制被认为有很大不同。
